GCC can compile K&R C today. K&R C being just about as far back as you can go with C, and it still being considered C.
You can mix K&R C with C89 or C99 in the same executable or library. It just works.
For example, there's a lot of K&R C code in bash.
Yeah, K&R C is from 1978. That's 41 years ago. I was playing with spaceships and aliens in 1978.
How long did it take Python 2 to become incompatible with Python 3? 7 years?
